IMPROVBD SPRING-BED BOTTOM.

TO ALL WHOM IT MAY CONGERN:

Be it knpwn that I, GEORGE A. BROWN, of Kalamazoo, and State of Michigan, have invented a new and `improved Spring-Bottom for Beds, Sofas, Railroad-Car Seats, and other upholstery; and I do. hereby'declare that the following is a full and exact description thereof, reference being hadto the accompanying drawings,

and to the letters of reference marked thereon.

'The nature of my invention consists in providing the bed, sofa., railroad-car seat, or'other thing desired,

wirhbottom of suitable dimensions, composed of a wooden framework combined withmetallic spiralsprings, .coi-ds, and pulleys, arranged and ope'ratedin such a'manner as to fully accomplish and perform the object intended, and hereinafter claimed, set forth, and described. To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct the framework from wood, proportioned, with reference to the article intended to bottom, into two similar parts, and arrange them in their positions, one above the-other, a few inches apart, according to length and size of springs intended, supporting them by posts at each of the four corners, as shown in accompanying drawings at-A, D,.F, and H.

' On the upperrsurface of the top frame I arrange pulleys, constructeid'from wood or metal, in number corresponding withvth'e springs employed, and worked upon small metallic rods set in and running alongV the surface ofl the top frame, its sides and ends, as lshown in the accompanying drawings, at I, J, K, andL.

Under the pulleys above speciiied, between the frames, I arrange the metallic spiral springs, coiled from wire, the length of which corresponds with the distance between the frames, the number, according to circumstances, from six to thirty, as the bottom intended' requires, and support them, and retain them in their positions by threepins, hollow tubing, or their substitute, to each spring,which pins, or their substitute, are arranged so as to enclose the spring, attaching the frames at three sides of the springs, as shown at M M and N N, in accompanying drawings. I Y

I construct buttons from wood, as an attachment of the cords, and arrange themunderneat-h each spring,

so as to slide up and down between the pins enclosing the springs, heretofore specified, as shown at P P in accompanying drawing. f

Over the top of theframe, lengthwise and across, I arrange cords, webbing, or their substitute, asbest serves the purpose, over the pulleys opposite, en the frame, down through the springs, attaching to the buttons below by a knot, and so arrange them that when attached as above speciiiedfthe force of thesprings operates upon them, makingthem taut across the frame, as shown at R R in accompanying drawings. I

v I operate my'invention by arranging its different parts as above specified, and, when used as a bed-bottom, the weight of the person lying on the cords or webbing above described, operates upon the springs, producing the desired results. And, when used as a bottom of a lounge, sofa, railroad-car seat, die., as above specified, theoperation of the springs is the same by the weight ofthe person in a sitting or lying posture, and the'same results are had, viz, the spiral springs are drawn together in the coil from the bottom, to which thecord is attached by means of the button, the opposite ends of the springs' bearing against the upper framework, the buttons slide up between the pins or their substitute, and recoil and return to their positionA again when the weight removest Y( i What I claim as my invention, and desire to se'cure by Letters Patent, is

The application of spiral springs M M, combined with cords R R, and their attachment P P, and pulleys K L, and'pins N N, when constructed and arranged substantially. as herein set forth and described.

GEORGE A. BROWN.
